Description
Summary:This paper deals with a model-free closed-loop fuzzy logic controller development to solve the speed tracking problem for a permanent magnet synchronous motor. The design procedure takes advantage of the fuzzy Lyapunov synthesis approach supporting the stability of the system. In contrast to traditional design control techniques, this solution does not require an a priori knowledge of the plant’s mathematical model. On the other hand, with an advantageous practical meaning, the fuzzy logic controller can be estimated through qualitative knowledge about the physical plant behavior. Lyapunov theory takes action allowing find rules that ensure stability instead of the traditional fuzzy logic controller where formal control strategies are involved. Additionally, the proposal is compared against well-known PI-controller under the same dynamical conditions, obtaining a more efficient control in terms of energy consumption without losing performance. The designed fuzzy controller performance is validated with simulations and experiments, verifying that the designed fuzzy controller can accurately solve the tracking problem on permanent magnet synchronous motors.
